Depends on the elements... Certain type of chemicals combined can be very dangerous and have a big impact like blowing up, or fizzing.... But typically they form a new element. Some elements counteract other elements.

An ion of iron has an 26 protons, 30 neutrons, and 23 electrons. what are its atomic number, atomic mass, and net charge?
Murrr4er [49]

Answer:

Z=26, A = 56, charge +3.

Explanation:

The atomic number is represented by Z. Is equal to the total number of protons that the atom has.  Z=26.

The atomic mass is represented by A. The number results from the total sum of protons and neutrons of an atom.  Both particles have a weight of 1 uma, are in the nucleus and give the mass to the atom.

Mass number (A) = atomic number (Z) + number of neutrons (N)

                        A = 26 + 30

                        A = 56

The net charge of the atom can be calculated by subtracting the negative charges from the positive ones. The positive charges come from the protons and the negative ones from the electrons.

26-23=3

This iron ion has a positive charge +3.

Based on the information in the weather map, which direction will the wind move? A) east to west B) west to east C) north to sou
Fofino [41]

Hello. You forgot to replace the map needed to answer that question. The map is attached below:

Answer:

B) west to east

Explanation:

The letter H on the map represents an area with high air pressure, while the letter L represents an area with low air pressure. As in the areas of lower temperature or colder the pressure is greater, the wind leaves these areas and goes towards those of higher temperature, which present less pressure. For this reason, we can say that the wind is moving from west to east.

The greater the pressure difference between the regions, the greater the wind speed, and in these situations, strong winds or winds can occur, which are given different names, depending on the location: hurricane (Caribbean), tornado (USA), typhoon (Asia).
